UNITED STATES JOSEPH PETRICEK, OF CHICAGO, ILLINOIS.

f FT' A NAILING Application filed June 21,

To all whom z't may come/Mt Be it known that I, JOSEPH Pnrnronx, a citizen of Czechoslovakia, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Nailing Devices, of which the following is a specification.

This invention relates to improvements in nailing devices and more particularly to such as are used by cobblers in repairing shoes. The primary object is to provide a hand-operated device that is speedy in operation and practically noiseless. A further object is to provide a device that is positive and efficient in operation and that anyone of Ordinary intelligence may readily learn to operate.

With the foregoing and other objects in view the invention consists in the combination and arrangement of parts to be hereinafter fully described, pointed out in the appended claim and illustrated in the accompanying drawing which forms a part of this application and in which Fig. 1 is a fragmentary .view of the device in front elevation.

Fig. 2 is a view of the device in side elevation, partly in section.

Fig. 3 is an enlarged fragmentary view of the device illustrating the nail magazine and chute.

. Fig. 4 is a fragmentary sectional view taken on line 4.-11 of Fig. 6. y

Fig. 5 is a fragmentary view illustrating the operating lever and Connections.

Fig. 6 is a fragmentary view of the idevice in elevation.

Fig. 7 is a fragmentary Sectional view of Fig. 6 with the movable parts in an altered position.

Like reference characters denote corresponding parts throughout the several views: A,

The device comprises the clamp 1 formed with the jaw extension 2, whereby it may be secured to a work bench, between which members a socket is formed to receive the post 3, a screw-bolt 4 serving to tighten the socket about the post. An adjustable socket 5 is formed at the opposite end of the said bracket 1 to receive the shank of the last 6 that holds the shoe 7 being repaired. A web plate 8 is formed with a tubular extension 9 adapted for adjustable arrangement upon the said post 3, a screw bolt 10 fitted into said extension being adapted for fric- DEVIGE.

tional engagement with the post to retain said members in adjusted position.

A magazine 11 formed at its 'throat with lateral spaced lips 12, 13 is arranged upon one side of the web plate and secured thereto by screws 14 that extend through ay plate 15 and through posts 16, 17 upon one side of said plate, into the said web. The plate 15 is an extension of the lp 12 and merges into the chute 18, at the base thereof, that communicates with the magazine, the throat 19 of which is in alignment with the space between the lips 12, 13. The chute 18 has the portions 20, 21 of its sides pressed inwardly, as clearly shown in Fig. 4, thus forming a raceway for the nails 22, the side v portion 20 being spaced away from the top 23 of the chute to permit observation of the travelling nai's and access thereto should the raceway become clogged.

In the portions 20, 21 of the sides of`v the chute the fiat Springs 24, 25 are secured, the spring 24 having its free end bent inwardly and extending through a perforation 26 in the. chute-side into the chute just beyond or above the tread surface of the raceway, the spring 25 having its body portion bent outwardly from the chute-side and its free end bent at an angle to the body portion and disposed in one of a pair of aligned perforations in the chute Sides, but upon the opposite side of the tread surface of the raceway with relation tol the end of the spring 24-, so that pressure upon the bulged portion of the spring 25 will cause the end thereof to pass through both openings in the chute and contact with the spring 211 and press the same outwardly from the chute withdrawing the bent end of the same from the interior thereof and out of the nail-passageway.

A post 27 is carried by the plate 15 and pivotally arranged thereupon is the rocker 28 having the segmental head 29 adapted for oscillation in and out of the throat 19 of the magazine, two extreme positions of said rocker being shown in Figs. 6 and 7, said rocker being formed also with the elongated recessed portion 30 which, in one poK` sition of the rocker, contacts with the post 17, the post 16 Contacting with the rocker lposedflin' anfelongated slot 43 in said head Vlevers zu'pon Vtheir ,pins

'p`1ate,`zsaid pin carrying the vreciprocating hammer 44 arranged in the `head plate.

Referring again to the lever endi33 the same carries .a heel 45 which, as the lever operateS, engages with one end of the dog :546 'fulcrumed upon a pin 47a `connecting the .upturned ears of a casting 48a, carried by *the plate 15, and depresses the opposite end .`of.-s`ai`d dog thatlrestsagainst the spring 25 Uand y.de'press'es :the same thus causing dis- ,place'ment o-f'the spring 24 in a manner previously described. The lever 37, reciprocat- ,edby'hand`, thus at each stroke displaces .therocker-.head 29 from the magazine throat I and fat the same time displaces the yielding spring 24, the springs'31 and 25 returning theV rocker, .lever and dog 46 to normal po- -sition vafter .each .of said strokes.

The lhammer 44 is formed with the refcessedpo'rtion 47 which,`in one position of recessed .portion of-thehead plate upon the t:pins 1:50 thus permitting movement of the Each lever 49 is lformed with a longitudinalrecess 51 that zmerges. into za contracted groove 52; and .with .alateral recess 53 aligned with the zperforatio'n54 in the head plate that registers with the mouth of the chute 18. A Icover Iplate 55 yis provided for the head Plate.

V,The magazine 11 is provided with the hinged cover 56 adapted to be retained in closed position by the spring clasp 57. 'With 'v =the 'cover'` open the nails are placed in the magazine, the cover then closed and the lever z37 operated. Each time the lever 37 is de- ,pressed the rocker is moved into the position shown in Fig. 6 thus permitting the pointed ends of the nails to project into the Ithroat 19 of the magazine. One or more of theznails may gravitate into -the chute 18 -but magazine which will impel the nails forward 'ii-nto the chute.

The head of the rocker first enters the throat 19 at the most remote point from the chute land rides upward vand forward in the throat until it fills the throat thus impelling the nails forward and into the chute; Th'e'heads of the nails will ride upon the tread portion of the raceway, the nailV bodies extendin'g down between :the walls 20, 21 as shown inF ig. 7. Each movement of the "operating lever..37 will force V the spring 24 out of the path of the nails and permit one nail at a. time to drop 'from the mouth of the chute through the perforabeneath the end lof the hammer which, at

ltion in thehead plate and'through the reits next descent will Ystrike'the head of the nail and force it into the'shoe. The operator so guides the shoe upon the last that the successive nails will be driveninto the partsV of the shoe sole or heel' desired. Each time' the free end of vthe lever37 is depressed a nail is driven'by Vthe hammer into the shoe andas 'i the lever is returned to normal position Vanother nail is released and positioned beneath the hammer ready .forthe next stroke.

lVhat is claimed is 1 a In a nailing device, a work support, avnail magazine, a nail chute registering'therewith, a plate 'connectlng` said chute and nail magazine, nail-feedlng mechanism associated with said plateV for V4feeding the contents of said magazine into'said chute, a recessed head plate formed with a perforationin alignmentV with the mouthof said. chute, a reciprocating hammer arranged in the recessed portion of said head plate, twin levei-s arranged in said head plate and operatively' associated with said hammer, said leversV being formed with nail-receiving recesses in the plane of :said

hammer, and lever controlledmechanism' for actuating said hammer.

In testimony that I claim the foregoing as ymy own I have hereto .afiixed my signature in the presence of two'subscrbing witnesses.
